Open the CIPO recordAbstract From the Canadian patent
A novel multistep flash analog to digital converter is taught, including a voltage estimator which quickly provides a rough estimate of the analog input signal. This rough estimate is used to select appropriate reference voltage tap points for use in the first flash conversion. This first flash conversion together with the voltage estimate, provides the most significant bits of the digital output word. A digital to analog converter is used to provide a residual voltage which is then converted by a second operation of the flash converter, thereby providing the least significant bits of the digital output word. In one embodiment, the voltage estimate is performed at the same time that the …
